摘要: 研究了退火温度对3.1 %Si无取向硅钢组织和磁性能的影响规律。结果表明:退火温度从940 ℃提高至1 000 ℃,平均晶粒尺寸由98 μm增加到145 μm,铁损P1.5/50从2.576W/kg降低至2.408 W/kg。随着退火温度的升高,γ不利织构组分强度逐渐降低,{111}〈112〉织构组分强度降低约16 %,磁感B50逐渐升高,磁性能水平提高。

Abstract: The effects of annealing temperature on microstructure and texture and magnetic properties of 3.1 % Si non-oriented silicon steel were investigated in this paper. The results showed that, when the annealing temperature increased from 940 ℃ to 1 000 ℃, the average grain size of metallographic structure increased from 98 μm to 145 μm, the iron loss value P1.5/50 decreased from 2.576 W/kg to 2.408 W/kg. And as the annealing temperature increased, the strength of the unfavorable texture component γ gradually decreased, the strength of the {111}〈112〉 texture component decreased by about 16 %, so that the magnetic induction B50 gradually increased,and the magnetic properties was improved.
